useful improvement in Coke-Gvens, oi:-`-

ivhich the following is a speciiication.

This invention relates to/ structures 'for producingl colte in which.the coke ovens are long narrow chambers, .vertically arranged, withprovisions at their upper parts for charging them 'with coal or materialto be colred and provisions at their ends for dis* charging the coke.The structure of this invention includes a number of such coke ovenssuitably spaced apart; vertical com bustion chambers, divided into anumber of sections located, between the ovens and adjoining` the sideWalls, the laterally adjoining sections between the Walls of' adjacentconnected together. by suitable passages at their upper ends;`regenerator heaters loca beneath the ovens and divided into a. umher ofsections, alternate regenerators being' heated by the products ofcombustion of the 'fuel passing from some of the combustion chambers,While the other regenerators, previously so heated, are imparting heatto air supplied to the other combustion chambers; gaseous fuel supplypipes and gas ports located at the lower part of 'the combustionchambers; means for alternately directing the gas to the ports of theAconnected adjacent combustion chambers, whereby' the chambersalternately act as downtakes for the. products of combustion from theother chambers, to which they are connected, and means'adapted tosupp'lyair to the chambers actingas down-takes. It also includes moansfor allowing air to iioW alternately to the sections of adjacent regenlerators and to open the. other regenerators,

are passing, to Waste heat fines.

Fig. 8 is a general plan of the structure, diagrammatically showing theflow of the gas, air, etc.

The drawings illustratev a structure designed to suitably embody thenovel features of this invention. The coke ovens are Along chambersWhose vertical dimensions greatly exceed their horizontal lateraldimensions. They are all alike but are alternately designated by 9 and10 to facilitate description. Each is provided with a number of topopenings ll through which the coal. to be coked is passed so as touniformly lill vthe ovens. Their ends are closed by doors 12,- suitablyluted, during the coking operation, andieach one has all upper opening13 for the discharge of the volatile and gaseous constituents oit' thecoal. Regenerators, of ordinary checker brick construction, are locatedbeneath the ovens. Each regenerator is preferably divided into two partsthe d'ividing walls of which are laterally centrally located relative tothe ovens. Each part is divided into a suitable number' of sections thatdecrease in size from the ends of the ovens toward their centers.to'provide for uniform, distribution of air which is sup# plied to themfrom the outer ends of each series of sections. Four such sections areshown, indicated by 14, 15, and 17, each section having a separate airduct indicated respectively by 18, 19, 2O and 21. The regenerators, asunits extending under the'4 ovens, arealternately .marked 2Q, 23,v onthe operative illustration Fig. 8, ,which will be referred to hereafter.Occupying the spaces between the ovens 9 and '10 setsor" narrow verticalcombustion chambers 24 and 25 separated by vertical walls 26. Thosemarked 24 adjoin and cover the side walls of ovens-9 and those marked 25adjoin and cover the side walls of ovens 10. The outer ends of each setof`air ducts 18, 19, and 21 open into a valve box 27, which is providedWith a valve 28 adapted to close the air entrance to said box and alsoto close an outlet from the box to a waste heat flue 29 when the airentrance is; open. There is thus va :tree and unobstructed flow of airthrough all of the air ducts or passages to the separate regenerators,said passages being open through the valve boxes directly to theatmosphere at both sides of the structure. The waste heat iues 9.9located at the ends of the structure connect with a stack 30, the draftof which acts to cause the proper How of the air to and the products ofcombustion from the'v structure. The flues 29 are provided with gates ordampers 31 to regulate the low of gases through the` Structure. At theupper end of each of the sections of the regenerators are ports 32 ex-'tending in both directions and opening into the lower ends-ot asuitable number of the narron combustion chambers at the two sides ol'the oven above the regeperator.

A gas pipe 33\is located beneath each set of combustion chambersadjoining each of the side walls of the ovens, and from these `pipesports 31 open into t-he chambers ad one of the chambers, to heat its..tadjoining oven, the other is acting as a down-take toimpart the heat ofthe products ot' eoi'nbusf tionto the side wall. of its adjoining oven.

`Means are provided 4for governing the How of gases. etc. through the,combustion chambers, shown as consisting of flat bricks 3S in thechambers 37 adapted to be set, by means of a suitable implement operatedthrough `openings 39 extending tothe top of the structure, to more orless rover the port passages 36.

The gaspipes 33 are connected at their outer ends toa gas main 40, andeach is provided with a cut-ofi' valve 41. To insure a uniform supply ofgasto all `of the combustion chambers, particularly ivhen the coke ovensare of considerable length, it is proposed 'to provide each end of thestructure with a gas main 'Ll-0 so as to supply gas to the two outerendsot' the pipes 33. To open the gas pipes to the atmosphere, when the gasis s h'ut cti', coclis or valves of a three- Way construction may beemployed. Such valves are conventionally illustrated in the drawings,designating the air inlets through 'which fresh air will pass 'to thepipes 33 and to the lower parts of the combustion chan'ibers 24 andthrough the ports 34. This supply of air to the lower parts of thecombustion chambers takes place when the chambers are acting asdowntakes for their adjoining' chambers and the productsof combustionare passing to the regenerators. The object and effect ot' this supplyvof cool air is to pre/vent over-heat.- ingl ol' the part ot' thechambers where the gas enters to such an extent as would cause carbondeposition from vthe fresh iniowing gas, when the cluimbers are actingagain as combustion chan'ibers, and also to keep-said ports clear andfree b v blowing therefrom any deposit that would tend to choke them.

The alternating ioiv of air, gas and the products of combustion isclearly illustrated in Fig. It being assumed that the coke ovens areinfull operation, air is en .tering the regenerators 22, through theopenings in the valve boxes at thsune time that gas from the mainsiioving to the. combustion chambers adjoining the colre ovens that areabove the regenerators 22. The 'products ot' combustion from thechambers adjoining the coke ovens above the alternateregenerators 23 areat the saine time passing through and heating said regenerators, andtherefrom flow by the iiues 29, to the stack 30, the valves in the boxes2T then heilig set to close the fresh air openings. about thirtyniiiuites, air is, by the threeivay cocks l1, entering the coinluistionchambers adjoining the ovens above the regenerators 23 as and for thepurpose previously described. At theI end (it the suitable heatingperiod7 the valves and 41 arr` nianipulated to reverse the flow throughthe regenerators1 the air then being caused to flow through the heatedregenerators 23 and gas to the combustion chambers adjoining the ovensabove said regenerators; the products o t combustion then fioa' throughthe regenerators 22 and raise their temperature to a degree sufficientto adequately heat the in- `ioiving air when the operation is againreversed.

During this time,-\vhich may be.

It ivill' be observed that by providing each section of the regeneratorswith an individual air passage'thej'" will receive amounts leI ties ofthe sections as they recede .from the air inlets.' x It will also beobserved that by dividingthe eolie ovens heating means into a number ofnarrow combustion chambers the supply of gas and air thereto is under pe.iectvcontrol and thereby the consumption of fuelffmay be reduced to aminimum and the ovens also uniformly heated throughout their length.
